| Abstract: | A small, low-noise 0.78 μm-band laser diode unit, containing a Faraday rotator which suppresses optical feedback, was developed. Stable low-noise characteristics were realised within the 3 mW to 10 mW output power. Greater than 40 dB signal/noise ratio was obtained in an optical video disc with this unit |
